Rept. for Sep 66-Sep 67,
DREXEL INST OF TECH PHILADELPHIA PA DEPT OF MECHANICAL ENGINEERING
Pagination or Media Count:
The dynamic elasticity equations for isotropic material together with their variations and different simplifications are presented. The basic concepts in wave propagation, especially those concerned with wave velocity, phase velocity, dispersion, and vibration analysis, are discussed. Dispersion equations for a composite two-layered cylindrical shell are derived. The application of the method of characteristics to the two-layered equations are also presented. Author
